As usual, save a copy of the "WannaBe Preferences" file before you modify it. Improperly modifying this preference file can cause WannaBe to crash, so be very careful. Each setting is a separate PREF resource.

To modify the font settings, open the relevant resource and simply select the current font name completely and replace it by typing the name of your desired font.

To modify the body text size, it helps to understand hexadecimal numbers. The default size is 10, which is represented by 000A. Anything less than 10 is represented the same way it is represented in decimal (for instance, 9 is 0009). 12, 14, 15, 16, 18, 20, 22, and 24 are represented by 000C, 000E, 000F, 0010, 0012, 0014, 0016, and 0018 respectively. Be sure to use only 2 bytes (4 characters in the center column) when you modify the setting, just like the default.

To modify the sizes of heading text, use similar representations as for the body text size. The first 2 bytes are for H1 headings, while subsequent bytes are for the headings from H2 through H6.

To turn off HTTP authentication caching, change the "FF" in PREF resource 6 to
